I was hoping someone else would jump in on this, because I don't quite remember the details, but a couple of years ago, one of the guys wrote about a slick (and cheap) method. Basically it was to disassemble the action into its major components (essentially a field-strip), glop up the bits & pieces with fine valve-grinding compound (it was suggested Flitz would probably work too), reassemble, and work the action about 500 times; then disassemble and clean thoroughly (to get the grit out) and lube as usual. Folks that tried it said it worked well. Anyone else here have the details better? Anyway, hope this helps.
